Background: and Purpose Live cell-based assays (LCBA) are increasingly used for serological antibody detection due to their ability to preserve antigen conformation, offering moderately higher sensitivity than fixed cell-based assays. However, the clinical necessity of prioritizing LCBA for the detection of aquaporin-4 immunoglobulin G (AQP4-IgG) in neuromyelitis optica spectrum disorder (NMOSD) remains unclear, especially when compared to its established role in diagnosing myelin oligodendrocyte glycoprotein antibody-associated disease. Methods: We compared the performance of live cell-based assays using immunofluorescence (LCBA-IF) and fixed cell-based assays using immunofluorescence (FCBA-IF) in detecting AQP4-IgG in 90 cases of NMOSD meeting 2015 International Panel for Neuromyelitis Optica Diagnosis criteria, alongside 40 controls. Additionally, we further investigated the relationship between AQP4-IgG titers as measured by LCBA-IF and FCBA-IF and clinical parameters in NMOSD patients. Results: Results showed 96.9% agreement between LCBA-IF and FCBA-IF (Cohen’s κ=0.935), with a strong Spearman correlation (0.977, p<0.001). Both methods demonstrated 100% specificity, with LCBA-IF showing slightly higher sensitivity compared to FCBA-IF. Within LCBAIF-tested groups, statistically significant differences in annualized relapse rates were observed across all pairwise comparisons (low-titer vs. moderate-titer, low-titer vs. high-titer, and moderate-titer vs. high-titer; all p<0.050). However, this association reached statistical significance in some FCBA-IF-tested groups. Conclusions Overall, there is a strong concordance between LCBA-IF and FCBA-IF in detecting AQP4-IgG, where LCBA-IF shows slightly higher sensitivity. Furthermore, there is a potential link between elevated AQP4-IgG titers and an increased risk of relapse, and this correlation may appear more pronounced when using LCBA-IF.

BackgroundThe mental health issues of medical staff have received increasing attention. Previous studies have mainly focused on the epidemiological characteristics and influencing factors， but there is a lack of sufficient understanding of the heterogeneity characteristics of the depression-anxiety symptoms network among medical staff. ObjectiveTo compare the differences in the depression-anxiety symptoms network between medical staff and community residents， so as to provide references for the promotion of the mental health of medical staff. MethodsFrom June 1， 2022 to December 31， 2024， a stratified random sampling method was used to recruit 1 959 medical staff from public hospitals and community health centers in 9 townships （industrial parks） of Dongguan City， Guangdong Province， as well as 2 412 community residents in this area， were selected as the research subjects. The general situation questionnaire， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， and the Generalized Anxiety Disorder Scale-7 item （GAD-7） were used for investigation. The network visualization was conducted using the qgraph package of R 4.0.0. The centrality indicators of the network were calculated using the networktools package. The reliability of the network structure was evaluated using the bootnet package. The differences in the depression-anxiety symptoms network between medical staff and community residents were compared using the NetworkComparisionTest package. ResultsA total of 1 792 medical staff and 2 110 community residents completed the survey. The numbers of medical staff with mild， moderate and severe depressive symptoms were 381 （21.26%）， 217 （12.11%） and 169 （9.43%）， respectively， while the numbers of community residents were 322 （15.26%）， 98 （4.64%） and 66 （3.13%）， respectively. The numbers of medical staff with mild， moderate and severe anxiety symptoms were 411 （22.94%）， 126 （7.03%） and 93 （5.19%）， respectively， while the numbers of community residents were 320 （15.17%）， 73 （3.46%） and 18 （0.85%）， respectively. The comparison of the detection rates of depressive symptoms and anxiety symptoms between the two groups showed statistically significant differences （χ²=152.012， 205.953， P<0.01）. The network analysis results showed that the core symptom clusters of medical staff were "uncontrollable worry" "psychomotor retardation" "inability to relax"， and "depression"， while those of community residents were "uncontrollable worry" "inability to relax" "inferiority complex"， and "depression". There was a statistically significant difference in the network structure between the two groups （M=0.275， P<0.05）， and the overall connection strength of medical staff was lower than that of community residents （7.523 vs. 7.950， S=0.426， P<0.05）. ConclusionThe detection rates of depression and anxiety symptoms among medical staff were higher than those among community residents. The depression-anxiety symptoms network of medical staff was more concentrated， and the core symptoms were more prominent.［Funded by Social Development and Technology Project of Dongguan City （number， 20221800902552）］

Objective To investigate the impact of mitophagy,mediated by the long non-coding RNA SNHG16(LncRNA SNHG16)on diabetes-associated cognitive impairment(DCI).Methods 29 male C57BL/J mice were randomly divided into normal control(NC)group,DCI group and DCI+mitochondrial autophagy inhibitor(DCI+Mdivi-1)group.Morris water maze and new object recognition test were used to detect the cognitive function of mice,qRT-CPR was used to detect the expression of LncRNA SNHG16 and mitochondrial autophagy marker mRNA.Western blot were used to detect the expression of related protein.The mouse hippocampal neurons HT22 were divided into control(Con)group,high glucose(HG)group,HG+SNHG16 silencing(HG+sh-SNHG16)group and HG+no-load control(HG+sh-NC)group.CCK8 method and lactate dehydrogenase(LDH)method were used to detect neuronal damage.JC-1 method was used to detect mitochondrial membrane potential.Results Compared with NC group,the expression of LncRNA SNHG16 and the expression of autophagy-related gene 5,PTEN-induced putative kinase 1(PINK1),Parkin and microtubule associated protein light chain 3(LC3)Ⅱ/Ⅰ increased(P<0.05),while the expression of mitochondrial autophagy-related proteins P62 and mitochondrial outer membrane transposase 20(TOMM20)decreased in T2DM group.Compared with DCI group,the cognitive dysfunction of mice improved,and the expression level of LncRNA SNHG16 decreased in the DCI+Mdivi-1 group(P<0.05).The expressions of LncRNA SNHG16,LC3 Ⅱ/Ⅰ,PINK1 and Parkin were higher in HG group than in Con group(P<0.05),while the cell survival rate and TOMM20 protein expression were lower in HG group than in Con group(P<0.05).Silence of LncRNA SNHG16 can restore the activity of HT22 cells and mitochondrial membrane potential,and reduce the level of mitochondrial autophagy under HG condition.Conclusions The expression level of LncRNA SNHG16 was up-regulated in the hippocampus brain region of mice with diabetic cognitive dysfunction,and mitophagy was overactivated.Silencing of LncRNA SNHG16 inhibits mitophagy in hippocampal neurons and alleviates HG induced hippocampal neuronal damage.
